[0016] The manual operating mechanism for the brake and throttle of a disabled vehicle of the present invention will be described below with reference to the accompanying drawings.

[0017] In the embodiments of the present application, Figure 1 and Figure 2As shown, the manual brake and throttle operating mechanism of the disabled vehicle (hereinafter referred to as "the present invention") includes a brake linkage mechanism and a throttle linkage mechanism, and the brake linkage mechanism also includes a brake pedal rotating part 3, a brake rocker arm assembly 6 and a hinge plate 7. The upper part of the mounting base assembly 15 is vertically fixed with a vertical plate assembly 16 near the side, and the upper surface of the mounting base assembly 15 is installed with a rotating shaft 2 near the front through a mounting mechanism shaft joint plate 1. The lower part of the brake pedal rotating part 3 is fixed on the rotating shaft 2 by screws, one end of the brake pedal shaft assembly 4 is fixedly connected to the rotating shaft 2, and the other end is hinged to one end of the brake pedal rocker arm 5, and the other end of the brake pedal rocker arm 5 is hinged to the hinge plate 7. The end of the brake rocker arm assembly 6 is mounted on the upper part of the mounting vertical plate assembly 16 through the rotating shaft, and the middle part of the brake rocker arm assembly 6 is welded and installed. A hinged piece 7 is installed, and the brake rocker arm assembly 6 is bent upward at the welded hinged piece 7. The end of the upward bent part of the brake rocker arm assembly 6 is fixedly installed with the brake assembly control handle 8; the throttle linkage mechanism includes an accelerator pedal pressing part 9 and an accelerator pedal rocker arm 10. The throttle link 11 is hinged to the upper end of the throttle pedal rocker arm 10 near the end, and the lower end of the throttle pedal rocker arm 10 is movably sleeved on the rotating shaft 2. The throttle pedal pressing part 9 is installed at one end of the throttle link 11 in the same direction as the brake pedal rotating part 3, and the other end of the throttle link 11 is hinged to the lower end of the throttle link 2 12. The upper end of the throttle link 2 12 is fixedly connected to the end of the throttle rocker arm assembly 13. The end of the throttle rocker arm assembly 13 is installed on the mounting vertical plate assembly 16 through a rotating shaft, and the other end of the throttle rocker arm assembly 13 is fixedly installed with a throttle rocker arm handle 14.

[0018] The utility model announcement number is CN210258380U, which is a car driving assistance device for the disabled (hereinafter referred to as "this patent"). This patent contains a large number of parts, and the parts have a complex structure and are relatively laborious to process, which will lead to an increase in equipment costs and cannot well control production costs. The present invention can effectively reduce production costs and promote the difficulty of promotion by streamlining the structure of the brake linkage mechanism and the throttle linkage mechanism and reducing the processing difficulty through a large number of stamping parts and cutting parts.

[0019] In order to further optimize the working efficiency of the present application, the brake pedal rotating part 3 is able to smoothly push the brake pedal up and down, and the brake pedal shaft assembly 4 is fixedly installed at the part where the brake pedal rotating part 3 contacts the brake pedal, and the brake pedal shaft assembly 4 can roll up and down on the brake pedal. In order to enable the accelerator pedal pressing part 9 to smoothly push the accelerator pedal up and down, the accelerator pedal pressing part 9 includes a rotating shaft and a bearing, and the bearing contacts the accelerator pedal. In order to prevent misoperation, the end of the brake rocker arm assembly 6 where the brake assembly control handle 8 is installed is bent to the left, and the distance between the brake assembly control handle 8 and the accelerator rocker arm handle 14 is fifteen centimeters, and the height is inconsistent. In order to improve operating comfort, the brake rocker arm assembly 6 is bent upward by five degrees.

[0020] When in use, the manual brake and throttle operating mechanism of the disabled vehicle is installed, wherein the brake pedal shaft assembly 4 is fitted with the brake pedal, and the throttle pedal pressing part 9 is fitted with the throttle pedal, and the equipment can be put into use.

[0021] When the utility model is in use, the specific operations are as follows:

[0022] When braking, the driver lifts up the brake assembly control handle 8, which drives the brake rocker arm assembly 6 to lift up with the hinged part at the end as the center of the circle. When the brake rocker arm assembly 6 is lifted up, it drives the hinged piece 7 to move upward. The upward hinged piece 7 pulls the brake pedal shaft assembly 4 upward through the brake pedal rocker arm 5. The brake pedal shaft assembly 4 drives the rotating shaft 2 at its end to rotate forward, thereby pressing the brake pedal rotating part 3 fixed on the rotating shaft 2 downward, thereby completing the braking work. When the driver no longer applies pressure, the spring of the brake pedal provides a reset force to reset the brake linkage mechanism as a whole.

[0023] When accelerating, the driver presses the throttle rocker arm handle 14 downward, and the throttle rocker arm handle 14 drives the throttle rocker arm assembly 13 to be pressed down, and the throttle link 2 12 fixed at the end of the throttle rocker arm assembly 13 follows the linkage, so that the throttle link 2 12 is pressed down together, and the depressed throttle link 2 12 drives the throttle link 1 11 forward. Since the lower end of the throttle pedal rocker arm 10 is mounted on the rotating shaft 2 through a bearing, the rotating shaft 2 does not follow the movement. Instead, the throttle link 11 pushes the throttle pedal pressing part 9 forward under the restriction of the throttle pedal rocker arm 10, thereby pushing the throttle pedal to form the effect of stepping on the accelerator. When the driver does not apply pressure, the spring of the throttle pedal provides reset power to reset the throttle linkage mechanism as a whole.

[0024] In summary, the manual brake and throttle operating mechanism of a disabled vehicle in the embodiment of the utility model simplifies the structures of the brake linkage mechanism and the throttle linkage mechanism, simplifies each component, and reduces the processing difficulty through a large number of stamping parts and cutting parts, which can effectively reduce production costs and effectively reduce the difficulty of promotion.
